Slimbo is a physics puzzle about goo, gravity and gentle chaos. Drop soft jelly blocks into a stone pit and watch them squash, sag and settle. Nothing snaps to a grid — every piece leans on the ones below it, so your tower is only as good as the physics holding it up. The goal is simple: reach the lollipop. Getting there is not. • 18 handcrafted sites, each with its own trick • Soft-body jelly that stretches, tears and collapses for real • Hooks, ledges, thorns — and a hungry little bug that eats your work • A winged candy that hops away just as you close in • A hint when a site refuses to give in • No timers, no lives — think as long as you like One finger is enough. Tap to rotate, drag to drop, and let gravity do the rest.
